We have added a new Greek letter command to Efofex parameters. You can now define a parameter like:

$x=greek()

This will randomly select a Greek letter from a list of acceptable letters (excluding letters like pi which have specific meanings). In this case $x might be turned into al, ga or rh. This allows you to create algebraic and geometric questions with varying Greek letters.

If you define multiple Greek letters in one set of parameters, the letters will always be sequential.

$x=greek()
$y=greek()
$z=greek()

You might end up with the three Greek letters being be, ga and de.
